Thanks so much guys for the feedback so far. I am pretty sure i found tdc. i dont know if it is absolute tdc. i brought the piston up and had my little brother, with a ratchet, turn the engine over untill i felt it start to come down. then i marked on the damper and market on the block. It may be a TINIE tiny bit past tdc. because i felt it stop going up then i marked it. I would say its pretty close. Is there a better waY?
